Irrigation water is seen near passionfruit crops after a rare rain in the outskirts of Olmos in Peru's northwestern region of Lambayeque, March 14, 2013. The Olmos Irrigation Project next year will start pumping billions of gallons of water onto a nearby 170-square-mile patch of desert in the Olmos Valley near the Pacific coast. The $500 million project is the most ambitious yet in a handful of massive irrigation works that are turning large swaths of Peru’s historically parched coast into profitable agricultural fields. Odebrecht drilled a 12-mile (20-kilometer) hole through the Andes to pull water from where it has always been abundant - the Amazon watershed to the east - to the arid west coast of Peru that is home to two-thirds of the population and 80 percent of economic activity but only 2 percent of its freshwater.
